Secondary-school pupils in England appear to be rejecting cigarettes in greater numbers than ever before.
The most recent survey in a series that began in the 1980s indicates just 16% of the pupils have ever smoked tobacco, down from 19% in 2016 and 49% in 1996.
However, a quarter of the 13,000 pupils surveyed, from 193 schools across England, have tried drugs.
This includes nitrous oxide, known as laughing gas, as well as cannabis.
The 2018 survey also shows:
- 17% overall - and 38% of the 15-year-olds and 2% of the 11-year-olds - usually drink alcohol at least once a month
- 6% drink at least once a week
- 13% overall - and 30% of the 15-year-olds - think it is OK to try cannabis
- 25% had used e-cigarettes, the same proportion as in 2016
NHS Digital, which compiled the statistics, said the findings showed half of the young people who had recently either drunk alcohol, smoked cigarettes or taken drugs experienced low levels of happiness.
